the interfacial properties between fibers and the matrix contribute to the overall properties in high performance composites plasma treatments (ar, o//2, cf//4/o//2, n//2/h//2) have been performed on carbon fibers to improve the fiber-matrix interaction the treatment efficiency was checked by the single-fiber technique, while the surface chemistry and morphology were characterized by x-ray photoelectron spectroscopy (xps), static secondary ion mass spectroscopy (ssims), and scanning electron microscopy (sem). the o//2- and n//2/h//2-plasma treatments proved most effective both for introducing oxygen-containing functionalities at the fiber surface and for improving the interfacial shear strength of carbon fiber/epoxy composites. a relationship between the oxygen concentration at the fiber surface and the interfacial shear strength is demonstrated.
